This game here must be one of my most satisfying 2on2 wins. Especially since I was so convinced that we were going to loose and yet we managed to pull in a win. I admit that our opponents did a lot of things wrong, but still I think we did an amazing job of winning in the end.
We were playing as Yellow Protoss (me) and White Terran (TS-Buzz.) against a similar race-mixup. The map was Python, which I don't like a whole lot, but is an okay map.
I was dropped and attacked head on very early in the game. I did okay against this, but in the end it led to me loosing both my natural expansion and my main.
Normally loosing your main early on means that you are game-over, but they lost a lot doing it and we also successfully prevented one of them from expanding for a long while.
When I lost my main I had to play-on with just the top right island expansion. Rebuilding a base on such a tight space is not easy. My expansion was also successfully dropped a lot of times and counter dropped by my ally. At some point I even expanded back to my original natural and lost it again. Twice!
My ally did a really good job of keeping the Protoss opponent occupied and almost annihilated his main at some point. But brown Protoss still had two bases running most of the time and red Terran had plenty of tanks all over.
The game lasted for a really long time. About 50 minutes I think, and halfway through my ally indicated that this was about it -- now we had lost for sure. But somehow the game went on with my ally methodically defending his postions and raiding their bases, while I ferried my valiant zealots around bombing red tanks where I could find them.
In the end our Protoss opponent wrote "This game sucks" and quit. So did his ally. Watching the replay it was clear that they had mined out all their bases, run out of money and had no units left. We still had bases producing and a few units. It is the weirdest 2v2 victory I have ever had.
